Kizaki is proficient with all modes of Raygust. He can use it both offensively and defensively. With his strength, he can overcome its heaviness to make effective attacks. By combining Blade Mode with Thruster, he can also launch a powerful ranged attack.
Murakami's preferred fighting style has him wielding both Kogetsu and Raygust in Shield Mode, which he use extremely proficiently despite their weight. When attack is his focus, he keeps Kogetsu in his right hand, whereas when he prioritizes defense, he holds Raygust with his dominant hand. Murakami has also used Raygust in Blade Mode. He is capable of shrinking its size to throw it better, or changing its shape to trap the opponent's weapon. He is adept at using Raygust in conjunction with Thruster for a variety of effects.
Osamu consistently uses Raygust as one of his main offensive and defensive Triggers. He generally keeps it in Shield Mode, but he has also shown to switch to Blade Mode to attack, usually in conjunction with Thruster. On one occasion, he has thrown it to attack from mid-range. He is also capable fo changing its shape, using it to trap Kazama against a wall, then opening a hole to fire Asteroid.
Kizaki is capable of utilizing Thruster in a completely unconventional way. By holding Raygust's handle, he uses Thruster to propel his fist, generating enough force to send a Rabbit flying several meters and break through Lampyris's shield while also damaging Hyuse's trion body. He can use two at the same time, one in each hand. His fighting style in this case makes him very similar to a boxer. He focuses on strikes with the full weight of the body behind them. He has also used Thruster to launch Raygust in Blade Mode at a distant target.
Murakami is a versatile Raygust user. He primarily utilizes it in conjunction with Raygust in Shield Mode to ram the opponent, throwing them off balance and pushing them back. He can also use it to launch the shield at his opponent as a mobile barrier and propel himself to accelerate and change direction even in mid-air. By using Raygust in Blade Mode, he can also activate Thruster to make his slashes faster and more powerful, as well as to shoot the blade at a distant target. Murakami first uses Thruster in chapter 99 (episode 45 in the anime).
Osamu utilizes Thruster chiefly to increase the speed of his slashes with Raygust, as well as to rapidly close in on the opponent. He is also capable of using it to dodge, throw Raygust in Blade Mode at the enemy and to push an opponent in a favorable position with his Attacker Trigger in Shield Mode. Osamu was first seen using Thruster in chapter 12 (episode 6 in the anime).
Shield Charge (シールド突撃,Shīrudo Chāji?): Osamu activates Thruster while Raygust is in Shield Mode in order to ram into the target at high speed, pushing them back. By prolonging its duration, this technique can be used to forcibly relocate an opponent.
